Question

find the area and perimeter of an isosceles triangle whose equal sides are 5 cm each and base is 6 cm​

Answer 1

Answer:

Perimeter = 16 cm

Area = 12 cm²

Step-by-step explanation:

Perimeter = 5 + 5 + 6 = 16 cm

Area = 1/2 x b x h

(We can split the triangle into 2 and use pythagoras theorem to find the 3rd side)

∴Height = 4 cm

Area = 1/2 x 6 x 4  

Area = 3 x 4

Area = 12 cm²
