Question

Chef jess made a cake with an area of 93 1/2 inches. If the width of the cake was 8 1/2 inches, what was the length of the cake?

Really Confused

Answer 1

we know that

if the cake has a rectangular shape, the area is equal to

A=L*W

where

L is the length side o the cake

W is the width of the cake

in this problem

we have

`A=93 (1)/(2)\ inches^(2)= (187)/(2) \ inches^(2)`

`W= 8 (1)/(2) \ inches = (17)/(2) \ inches`

L=?

A=L*W

solve for L

L=A/W

`L=(187/2)/(17/2)=(187/17)=11 \ inches`

therefore

the answer is

the length is equal to 11 inches
