Step-by-step explanation:
- a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
- perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87
Answer:
2y-2x-2y= - 22x = 0x + 2y = 1
