Question

the length of a rectangle is (x+3) inches long and the width is 3 1/2 inches. if the area is 24 1/2 square inches, write and solve an equation to find the length of the rectangle

Answer 1

Equation for length = 3.5x = 24.5 / 10.5

Solving for x = 2/3 or 0.666 repeat

Explanation:

Area of a rectangle is base * height or A = b * h

Sub in the values:

(x + 3) * (3.5) = 24.5

3.5x + 10.5 = 24.5

3.5x = 24.5 / 10.5

x = 2/3 or 0.666 repeat
