Answer to Problem 10MPS
Explanation of Solution
Given: The rectangular base of a radio receiver is twice as long as it is wide. A design engineer finds that in order to fit the receiver into the space available on an airplane, she must decrease the length by 7 in. and increase the width by 2 in, If this changes decrease the area of the base by 32
Let the width of base be
Length be
A design engineer wants to fit receiver into the space available on an airplane.
So, decrease the length by 7 in and increase the width by 2 in.
New length
New width
Original area
New area
Change in area
Original dimension of radio receiver
