Examine the rectangle at right. A. Write an expression for the perimeter in terms of x.

B. Assuming the perimeter is 78 cm, determine the dimensions of the rectangle. Show all of your work.

C. Verify that the area of this rectangle is 360 sq. cm.

Explain how you know this.

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
