Question

three paintings are shaped like an eight foot square a 7 foot by 4 foot rectangle and a triangle with a 6 -foot base and a height of 7 feet if those paintings are hang together in the side of a building how much of the building we all will they cover together?​

Answer 1

Answer:

113 sqr ft

Step-by-step explanation:

Ar of sqr painting = a^2

= 8 x 8 = 64 sqr ft

Ar or rect painting = l x b

= 7 x 4 = 28 sqr ft

Ar of triangular painting = 0.5 x b x h

= o.5 x 6 x 7 = 21 sqr ft

Ar of paintings occupied on the building = 64 + 28 + 21

= 113 sqr ft

I hope this is correct =)
