Chauncey

Chauncey is building a storage bench for his son's playroom. The storage bench will fit into the corner and against two walls to form a triangle. Chauncy wants to buy a triangular-shaped cover for the bench.

Suppose the storage bench is 2 1/2 ft. Along one wall and 4 1/4 ft. Along the other wall, how big will the cover have to be to cover the entire bench?

Correct answer:

A =  5 516 = 85/16 ft2

Step-by-step explanation:

a=221=2+21=22 2+1=24+1=25=2.5 ft b=441=4+41=44 4+1=416+1=417=4.25 ft  A=21 a b=21 25 417=1685 ft2=5165 ft2=5.3125 ft2
