Question

For the rectangular parking area of the shopping center​ shown, which one of the following equations says that the area is 30,000 yd^2​? A. x+(8x+400)=30,000 B. x+(8x+400)=30,000 C. 2x+2(8x+400)=30,000 D. x^2(8x+400)=30,000 Equation __ says that the area is 30,000 yd^2.

Answer 1

Explanation:

Area of a rectangle is given by:

Area=length×width

From above we see that area is the product of two sides. Therefore from the options we have been given, the expressions that shows the area is 30000 yd² is B. x(3x+100)=30000.

This is because our area has been expressed as the product of x and (3x+100), in other words we can assume that the dimension of our rectangle is x yds by (3x+100) yds.
