hope this answers helps

thank you guys !!!

Answer 2

Step-by-step explanation:

i) area of rectangle=lxb

168=(7x)x(5x+2)

168/7=(x)x(5x)

24=6x

24/6=x

4=x

ii) perimeter of rectangle=2(l+b)

=2{(7x4)+(5x4+2)}

=2{28+22}

=2x50

=100

perimeter of rectangle is 100

iii). area of square=side x side

100=side x side
