There is a slide in
message "KEEP-
wall are 15 m, 11 m
Slide in a park. One of its side wait
walls has been painted in some colour with a
CEP THE PARKUREEN AND CLEAN" (see Fig.12.10).lf the sides of te
and 6 m. find the area painted in colour.
KEEP THE PARK​

Answer 1

let a=15m

b=11m

c=6m

therefore,s=a+b+c/2

s=15+11+6/2

s=32/2

s=16m

area=√s(s-a)(s-b)(s-c)

area=√16×(16-15)(16-11)(16-6)

area=√16×1×5×10

area=√2×2××2×2×5×2×5

area=√2^4×2×5^2

area=2^2×5√2

area=4×5√2

area=20√2

hope this will help you!
