Find the area of a isosceles triangle having the base x cm and one side y cm

xy/2 cm²

Step-by-step explanation:

An isosceles triangle is a triangle that has two sides out of the three sides to be equal. The area of an isosceles triangle is given as:

= 1/2 × base × height

where,

base = xcm

height = ycm

Therefore,

Area = 1/2 × x × y

Area = xy/2 cm²
