Question

find the area and perimeter of an isosceles right angled triangle each of equal sides measures 10 cm

Answer 1

Area: (10×10 / 2) 50 cm2

Perimeter: (10×3) 30 cm

PLS Mark as brain list

Answer 2

side = 10cm

area of triangle=1/2×b×h

=1/2×10×10

=5×10

=50cm2

using Pythagoras theorem

H2=B2 + P2

H2=100+100

H2=200

H= √200cm

perimeter of triangle = sum of all sides

= √200+10+10

=20+√200cm
