Step-by-step explanation:
length-8cm
breadth-?
perimeter-42cm
perimeter-2(l+b)
42=2(8+b)
42/2=8+b
21=8+b
21-8=b
13=b (Ans)
l*b=88
11*b=88
b=8
perimeter=2(l+b)
=2(11+8)
=2*19=38(ans)

perimeter = 2(L+B)
42 = 2 (8+B)
42 = 16 +2B
42-16 = 2B
26÷2 = B
13 = B
AREA = L×B = 8×13=104
area = L×B
88 = 11×B
88÷11= B
8 = B
Perimeter = 2(L+B) =2(11+8) = 38
