A scale drawing for a plot of land is shown below. In the drawing, 3 cm represents 4 m. Assuming the backyard is rectangular, find the area of the real backyard

[scale]=[drawing]/[real]> [real]=[drawing]/[scale]

scale=3 cm/ 4 m> 0.75 cm/m

the dimensions of backyard in the drawing are 9 cm x 6 cm

step 1

find the real dimensions of backyard

for 9 cm

[real]=[drawing]/[scale]

[real]=[9]/[0.75]> 12 m

for 6 cm

[real]=[drawing]/[scale]

[real]=[6]/[0.75]> 8 m

so

the real dimensions of backyard are 8 m x 12 m

[the area of the real backyard ]=8*12> 96 m²

the answer is 96 m²

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
