Area:
First solve the triangle the base is 8cm and the height is 6. So base times height divided by 2 is the formula
Triangle area = 24
For the rectangle the formula is width time length so 16 x 7 = 112
Rectangle area= 112
Then you add them both together
112+24=136 so that’s your area
Perimeter=
Rectangle is just 16 + 7 =
