Question

Can u please help I got 1 minnnn lefttttt

Answer 1

26 cm

Explanation:

P = 2a + 2b

a = side

b = base

Answer 2

The area=base×height

=10×4

=40cm^2

perimeter=2(length+breadth)

I think to find the height Dc you use the pythagoras theorem of

Dc^2=de^2+ce^2

=√16+9

=5

therefore the perimeter will be

p=2(5+10)

=20cm

I hope this helps and sorry if it's wrong
