Question

Gargi plans to build a house that is 1.5 times
as long as it is wide. She wants the land
around the house to be 20 ft wider than
the width of the house and twice as
long as the length of the house, as
shown below. Write the expression for
remaining area of land and find the area

a 2x² + 60x, 3200 sq units
b 3x2 + 60x, 3050 sq units
c 3x2 + 60x, 3150 sq units
d 1.5x² + 60x, 3150 sq units​

Answer 1

Answer:

We set up the 1st equation as

l=1.5w.

And the perimeter of a rectangle is

2w+2l=25

substitute the 1st equation into the second.

2w+2(1.5w)=25

2w+3w=25

5w=25

W=5

so l=1.5(5)=7.5
