If you answer all three ill give you brilliant what is the backboard’s length in metres? what is the perimeter of the total area? what is the area of the seating space?

Step-by-step explanation:

18900cm = 189m

189 to the lowest 10 in m would be 1.89

L=x

W=1.8m

A=189m

189/1.8=105

W=1.05m

Check by 1.8×1.05=1.89

Perimeter= 2l+2w

2(18.4)+2(32.5)+2(15)+2(28)=187.8m is the total area perimeter.

Area of the seating space is

L×w(18.4×32.5)=598

L×w(15×28)=420

598-420= 178m squared is your seating space.
