Please help me i don’t know how to do this my teacher didn’t explain it well

Answer 1

see below

Explanation:

1. It's sort of hard to draw a rectangle digitally but the area of it would be

15 x (12+2) = 210 square feet

• For the top left rectangle 3 x 4 feet = 12 square feet
• For the top right corner triangle area of a triangle is half the base multiplied by the perpendicular height so 2(2/2)=2 square feet
• Here are my workings for the area of the shaded region
• 210-(8x4)-12-2=164 square feet
• If the cost per square foot is $5.40 then 5.4 x 164 = $885.60 for the whole kitchen
