Calculate the areas and perimeters of each shapes, start bu calculating any missing sides.

Perimeter of A = 46cm

Area of A = 112cm^2

Perimeter of B = 61cm

Area of B = 118cm^2

Step-by-step explanation:

So there are two shapes. I divided one into 2 parts ( shape A ) . And the other into three ( shape B

Shape A:

PERIMETER = S + S +S +S + S + S + S + S ( THE SHAPE HAS 8 SIDES )

= 5 + 5 + 20 + 11 + 3 + 3 + 5 + 4 ( THIS INCLUDES THE MISSING SIDES )

= 46 CM

AREA- To find the area you divide the shape

Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2

Final part ( add part a and b ) - 12 + 100 = 112cm^2

Shape B:

PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )

= 12 + 2 + 2 + 4 + 5 + 4 + 4 + 4 + 6 + 6 + 12 + 5

= 61 CM

AREA- To find the area you divide the shape

Part 1 - 12* 2 = 24cm^2 Part 2 - 4 * 3 = 12cm^2 Part 3 - 12 * 6 = 72 cm ^2

Final part ( add part a, b and c ) - 12 + 72 + 24 = 108cm^2
