Item 3 A rectangle is 29 feet long and 7 feet long.

What is the area of this rectangle?

203 ft²

143 ft²

107 ft²

72 ft²

203

Step-by-step explanation:

to find the area, you have to multiply the length of the sides together. 29x7 = 203

i believe the answer is the polygon, heptagon.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
