SOLUTION

Plot points P, Q, R, and S on a coordinate plane. Point P is located in Quadrant IV. Point Q is located in Quadrant III. Point R lies on the y-axis. Point S is located in Quadrant II.

ANSWER

Point S( - 2, 1) is in Quadrant II. The correct answer is D.

Find the length, width, area and perimeter of rectangle ABCD.

The length of the rectangle is the horizontal distance between A and B.

SOLUTION

The width of the rectangle is the vertical distance between A and D.

Length = 4 + 4 = 8 units

Wide = 2 + 2 = 4 units

The area of the rectangle is found by multiplying the length and width.

Area lw 8(4) 32 square units= = =

Area and Perimeter

The perimeter of the rectangle is found by adding all sides together or adding two times the length plus two times the width.

Perimeter = l + l + w + w = 8 + 8 + 4 + 4 = 24 unitsor 2l + 2w = 2(8) + 2(4) = 16 + 8 =24 units

You try: Find the perimeter and area.

Points A, B, C, and D form a figure.

What is the figure? a

rectangleTo find the length (l), find the horizontal distance from A to B To find the width (w), find the vertical distance from B to C.

Perimeter = 2 L + 2 W = 2 (7) + 2 (9)

Area = L x W length x width 7 x 9 =

SOLUTION- Graph it

Find the length, width, area and perimeter of rectangle ABCD formed

by the points A(1, -4), B(4, -4), C( 4, -2), and D(1, -2).

You Try:

Solution!The length of the rectangle is the horizontal distance between A and B.

Length = 3units

The width of the rectangle is the vertical distance between A and D.

Wide = 2 units

The area of the rectangle is found by multiplying the length and width.

Area lw 3(2) 6 square units= = =

The perimeter of the rectangle is found by adding all sides together or adding two times the length plus two times the width.

Perimeter = l + l + w + w = 3 + 3 + 2 + 2 = 10 unitsor 2l + 2w = 2(3) + 2(2) = 6 + 4 = 10 units
