Question

2. A right angle triangle has two equal sides and has an area of 32sq m. If one of

the two equal sides is doubled what will be the area of the resultant right angled

triangle?

Answer 1

let us assume in first case, the equal side is x

therefore x^2/2 = 32
or, x = 8

now the sides are doubled. so the sides are now 16 m

therefore the area = 16^2/2
= 128 sq. m

Answer 2

suppose two equal side length= x meter

right angle triangle area= 1/2(x²)

32= 1/2x²

64= x²

x= 8m

we Will two equal side length double y= 16m

resultant area = 1/2 (16)²


= 1/2(256)

= 128m²
