Question

The area of a square game court is 64 square feet. How long is one side of the court? just help with number 14 don't mind 15,16,17 kk thx

Answer 1

14A) Area of a square = (side)^2 = 64cm^2 {given}

=> side = √64 = 8 cm {length of one side}

15A) 17 ft

Solving it using Pythagoras theorem, we get

${hypotenuse}^{2} = {15}^{2} + {8}^{2} = 225 + 64 = 289 = \sqrt{289 } = 17ft$

16A)

${26}^{2} = {10}^{2} + {b}^{2} = 676 - 100 = {b }^{2}$

${b }^{2} = 576 = > b = \sqrt{576 } = 24in$

17A)

${c}^{2} = {7}^{2} + {4}^{2} = > 53 = > {b }^{2} = {53} = > b = \sqrt{53} cm$

Hope this helps you : )
