Answer:
Area of the shape=241.2cm^2
Perimeter of the shape=76.08cm
Step-by-step explanation:
Find the base for the first triangle = tan(75°)=O/A
= A=30/tan(75°)
=A = 8.04cm (2decimal place)
Area of first triangle= 1/2×Base×height
=1/2×8.04cm×30cm
=120.6cm^2
So total area for the shape is = 2×120.6cm^2
=241.2cm^2
Perimeter of the shape = 2(30cm+8.04cm)
=76.08cm
