Mrs. Tyler's room shares a common wall with a storage closet. The closet is 15 feet long and 25 feet wide, as shown below. The combined area of her room and the closet is 1250 square feet. How long is Mrs. Tyler's room? 35 feet 40 feet 50 feet 85 feet

answer: 15

step-by-step explanation:

the graph on the bottom right

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
