Question

Which equation would best help solve the following problem?

Adina has a rectangular garden that measures 9 m wide by 13 m long. She wants to increase the area to 192 m2 by increasing the width and length by the same amount. What will be the dimensions of the new garden?


A.
192 = (9)(13)


B.
192 = (9)(13 + x2)

C.
192 = (9 – x)(13 – x)

D.
192 = (9 + x)(13 + x)

Answer 1

Answer 2

Area = length*breadth
Let the increment in the sides be x then
new length = 13+x
new breadth = 9 +x
new area = 192
so 192 = (13+x)*(9+x)
