Answer 1

we know that

3 cm represent 4 m

so

3x3 cm2 -----> represent 4x4 m2

9 cm2 ------> 16 m2

step 1

Find out the area of the backyard in the drawing

A=3*6

A=18 cm2

Remember that

9 cm2 ------> 16 m2

multiply by 2 on both sides

18 cm2 ----> 32 m2

therefore

The answer is 32 square meters
