Answer:
6.144cm²
7. 24cm²
8. 43.96cm²
9. 27.5ft²
10. 72m²
solution:
6. (S×S)= 12cm×12cm=144cm²
7. (L×W)= 8×3=24cm²
8. C= 2 (3.14) (7cm)
=43.96cm²
9. b×h÷2
11×5÷2
= 27.5ft²
10. l×w
=12×6
=72m²
6.A=s(s)l x w
A=12 x 12
A=144cm
7.A=w×l
A=8m. x 3m.
A=24m.
8.A=πr2
A=3.14×7×7.
A=153.86 cm2
9.A=1/2 x b x h
A=1 x 11 x 5÷2
A=27.5ft.
10.A=w x l
A=12m. x 6m.
A=72m.
