Answer:
Step-by-step explanation:
9) h^2+3^3=5^2
=} h^2=25-9
=} h=√16
= 4in
Perimeter=4×5= 20inc
Area= b×h
= 5in×4in= 20in^2
10) h^2+0.6^2=1^2
=} h^2=1-3.6
=} h=√0.64
=0.8cm
Perimeter=4×1=4cm
Area=b×h
= 1cm×0.8cm=0.8cm^2
11) h^2+9^2=15^2
=} h^2= 225-81
=} h= √144
= 12yd
Perimeter= 4×15=60yd
Area=b×h
= 15yd×12yd=180yd^2
12) Area of a parallelogram
= b×h
= 4.5in×3in
= 13.5inches^2
