Question

2. One of the equal sides of an isosceles triangle is 13 cm and its perimeter is 50 cm. Find the area of
the triangle.
3. The perimeter of a square is numerically equal to its area. Find its area.​

Answer 1

Answer:Given that one of the equal line is of 13 cm, so length of other side should also be 13 cm. ∴Length of third side is 24 cm. therefore, applying heron's formula for the area of the triangle. Therefore, area of the triangle is 60 cm^2

Answer 2

Step-by-step explanation:

2. let the sides of triangle be AB, BC, CA.

As isosceles triangle is the triangle that have 2 equal sides and one equal side is AB= BC = 13cm

we are given that

perimeter = 50cm

AB + BC + CA = 50cm

13 +13 + CA = 50

26 + CA = 50

CA = 50 - 26

CA = 24cm.

3. As perimeter of square = 4 × side

area = side × side

= (side) square

so it is basically numerically equal to the area
