Question

An isosceles right angled triangle is shown. The area of the triangle is 200cm squared.Work out the value of the x

Answer 1

x=20 cm

Explanation:

Let x be the length of equal sides.

Area of triangle=
`200cm^2`

We have to find the values of x.

We know that

Area of right triangle=
`(1)/(2)bh`

Where b=Base of triangle

h=Height of triangle

Using the formula

Area of right triangle=
`(1)/(2)x^2`

`200=(x^2)/(2)`

`x^2=200* 2`

`x^2=400`

`x=√(400)`

`x=20cm`

Hence, the value of x=20 cm
