Question

the ratio of the dimensions of a rectangular patio are 4:7. If the shorter dimension is 10 feet, what are the area and perimeter if the patio?

Answer 1

4:7
shorter is 10
4<7
4=10 units
2=5units
1=2.5units

we need to find what 7 is
7 times 2.5=17.5


area=legnth times width
legnth=17.5
width=10
area=17.5 times 10=175

perimiter=2(L+W)
perimiter=2(17.5+10)
P=2(37.5)
P=75




AREA= 175ft^2
PERIMITER=75 ft
