Question

Find the area and perimeter please I need help​

Answer 1

For rectangle,

Perimeter=41cm

Area=72cm^2

For triangle,

Perimeter=30

Area=40

Explanation:

For the rectangle, the perimeter is 2(L +B)

Length=16cm

Breadth=4.5cm

Perimeter=2(16+4.5)

=2(20.5)

=41cm

For the rectangle,Area= Length x breadth

=16 x 4.5= 72
`cm^(2)`

For the triangle, I can't see the third figure.

Just a guideline though

For the perimeter you just need to add the 3 figures together which will be 12 + 10 + 8=30

For the triangle, Area=
`(1)/(2)` x base x height

The base is 10 while the height is = 8

Area=
`(1)/(2)` x 10 x 8

=80/2

=40
