Question

A rectangular garden is 8 feet long. If you walk diagonally across the garden, you would walk 10 feet. How many feet wide is the garden?

Answer 1

By using Pythagoras theorem

width = $\sqrt{10^2 - 8^2}$ = 6 feet

Answer 2

Use Pythagorean theorem
a²+b²=c²
8²+b²=10²
64+b²=100
64-64+b²=100-64
b²=36
b=√36
b=6
6 feet wide is the garden
