Question

the area of rectengle of length a and b is​

Answer 1

Answer:

a×b

Explanation-

let one side(length) of rectangle =a

other side be=b

Area= measurement of region or part in which object lie on plane

• hence,from defination

Area of rectangle=a×b

hope it helps u

Answer 2

$area \: of \: rectangle = (l \times b)$

Let's learn with a help of an example:-

The length of a rectangle is 15m and its breadth is 12m. Find the area of the rectangle

According to question:-

$(length \times breadth)$

15×12

180

Area of rectangle= 180m

_______________________________________

• Area of square= s² or s×s
• Length of rectangle= Area/ Breadth
• Breadth of rectangle= Area/ Length
• Side of square= √area
• Perimeter of rectangle= 2×(l+b)
• Perimeter of square= 4×side
• Area of parallelogram= Base× Height
• Area of triangle= 1/2× base× height
• Area of equilateral triangle= √3a²/4, where a means length of a side.
• Perimeter of triangle= a+b+c
