Answer 1

Solution:

It is given that ;

• one of the side of rectangle = 12 m
• Diagonal of Rectangle = 13 m

Other Side of Rectangle = (Diagonal)² - ( Side)²

Other Side of Rectangle = 13² - 12²

Other Side of Rectangle = 5 m

Now, According to the Question's Statement!

We have to find the Area of Rectangle;

Area of Rectangle = 5 × 12 m²

Area of Rectangle = 60 m²

Therefore, Area of Rectangle will be 60 m².

Answer 2

1. find out the other side of rectangle by paithagorous therym hypo²=perpe²+base² 13²=x²+12² x²=25. x=5. Now we know area of rectangle =base.height. area=12×5 =60m²
