Question

A football field is 120 yd long and 50 yd wide. what is the area of the football field, in m2, if 1 yd = 91.44 cm?

Answer 1

First, find the area of footbakk field in square yards:

$A=length\cdot width=120\cdot 50=6000$ sq. yd.

Next, if 1 yd = 91.44 cm, then 1 sq. yd=91.44·91.44 sq. cm=8,361.2736 sq. cm.

At last, you have that

1 sq. yd - 8,361.2736 sq. cm.

6000 sq. yd - x sq. cm.

Mathematically,

$\dfrac{6000}{1}=\dfrac{x}{8,361.2736},\\ \\x=8,361.2736\cdot 6000=50167641.6$ sq. cm.

Note that 1 m=100 cm and 1 sq. m=10000 sq. cm, then

50167641.6 sq. cm=5016.76416 sq. m

Answer: 5016.76416 sq. m
