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

Answer:

x=20 cm

Step-by-step 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=$\frac{1}{2}bh$

Where b=Base of triangle

h=Height of triangle

Using the formula

Area of right triangle=$\frac{1}{2}x^2$

$200=\frac{x^2}{2}$

$x^2=200\times 2$

$x^2=400$

$x=\sqrt{400}$

$x=20cm$

Hence, the value of x=20 cm
