Answer 1

Answer:

210 cm2

for bigger triangle base is 24 cm

height is 7 cm

another side is 25 cm

and smaller triangle is made from midpoints of bigger triangle side

base of smaller triangle =1/2×24 =12 cm

height of smaller triangle = 1/2 ×7=3.5cm

another side = 1/2 × 25 =12.5cm

area of smaller triangle= 1/2×3.5×12

210 ^2cm

Answer 2

Answer:

answer21

given date is one right angle triangle formed

24^2+7^2=25^2

formula :1/2×base×height

1/2×24/2×7/2=21
