Question

length=8 breath=5 so what is the area and perimeter​

Answer 1

Answer:

l = 8 cm

b = 5 cm

P

= 2(l+b) units

= 2(8+5) cm

= 2×13 cm

= 26 cm

A

= l×b units

= 8×5 cm²

= 40 cm²

Hence,

Perimeter = 26 cm

Area = 40 cm²

Answer 2

Answer:

∴ The area of a rectangle is $40$ sq. units

 The perimeter of a rectangle is $26$ units      

Step-by-step explanation:

• In context with question below,
• We have to find the area and perimeter of a given rectangle.

         The length = $8$ units

         Breadth = $5$ units

• Rectangle has four sides in which two pairs of opposite sides are parallel to each other and have same length.
• The formula for area of a rectangle is given by,

      Area of a rectangle = $l\times b$

                                   = $8\times 5$

                                   = $40$ sq. units

• Now, perimeter is the sum of all sides of a rectangle.

    Perimeter of a rectangle = $2(l+b)$

                                        = $2(8+5)$

                                        = $2\times 13$

                                        = $26$ units

• ∴ The area of a rectangle is $40$ sq. units
•  The perimeter of a rectangle is $26$ units
