pls answer me please​

Answer 1

Answer:

1.perimeter of the figure

(2.5+2.5+2.5+7.5+2.5+2.5+2.5+2.5+2.5+7.5+2.5+2.5)m

=(2.5×10+7.5×2)m

=(25+15)m

=40m

2. 60ac^3b^2

=2×2×3×5×a×c×c×c×b×b

36x^3yz

=2×2×3×3×x*x*x*y*z

3.second adjacent side =√(61^2-11^2) cm

=√(61+11)(61-11) cm

=√72.50 cm

=√9.4.2.25.2 cm

=3.2.5.2 cm

=60 cm

hypotenuse=√(13^2+84^2)cm

=√(169+7056)cm

=√7225cm

=85cm
