Question

find the missing side of the right triangle if
a)area 84cm , height 12cm
b)area 56cm, height 7cm
c)area 12m, base 20m​

Answer 1

Answer:

a. Area=1÷2×Base×Height.

84=1÷2×Base×12

84×2=Base×12

168=Base ×12

168÷12 =Base

Base=14

b. Area =1÷2×B×7

56 =1÷2×B×7

56×2=B×7

112÷7=B

16=Base

c.Area= 1÷2×20×Height

12=1÷2×20×H

12×2÷20 = H

24÷20= H

1.2=Height
