Question

Find the value of x. PLEASE HELP ME!!!!!!!!!!

Answer 1

Solution:

Step-1: Find the missing side length using Pythagoras theorem:

• 115² = 69² + x²
• => 13225 = 4761 + x²
• => 13225 - 4761 = x²
• => 8464 = x²
• => x = √8464 = 92

Step-2: Find the area of the rectangle:

• Area of rectangle = LB
• => 69 x (92 + 100)
• => 69 x 192
• => 13248 units²

Answer 2

Apply Pythagorean theorem

$\\ \rm\bull\rightarrowtail b^2=115^2-69^2$

$\\ \rm\bull\rightarrowtail b^2=13225-4761$

$\\ \rm\bull\rightarrowtail b^2=8464$

$\\ \rm\bull\rightarrowtail b=92$

• Now length=192
• Breadth=69

Area=Length×Breadth

$\\ \rm\bull\rightarrowtail Area=192(69)=13248units^2$
