Q no 9 pls give right solution ​

Answer 1

Answer:

The area of a rectangular plot whose on the side is 8m long and diagonal is of length 17m is 120 sq. cm .

Step-by-step explanation:

Given: Length of rectangle = 8 m

And diagonal of rectangle = 17m

Find the area of a rectangular plot

Step 1: Find breadth by using Pythagoras theorem

$(Length)^2 + (breadth)^2 = (diagonal)^2\\(8)^2 + (breadth)^2 = (17)^2\\64 + (breadth)^2 = 289\\ (breadth)^2 = 289 - 64 =225$

Breadth = 15 cm

Step 2: Find the area of a rectangular plot.

The area of a rectangular plot = Length  × breadth

= 8 ×  15

= 120 sq. cm
