Question

If the length and breadth of a rectangle are 15cm and 10cm, respectively, then its area is:

A. 100 sq.cm

B. 150 sq.cm

C. 115 sq.cm

D. 200 sq.cm​

Answer 1

Answer:

Option B. 150 sq. cm

Step-by-step explanation:

Length of rectangle = 15 cm

Breadth of rectangle = 10 cm

Area of rectangle = Length × Breadth = 15 × 10 = 150 sq. cm

Answer 2

Given thαt,

• Length of the rectαngle = 15 cm.
• Breαdth of the rectαngle = 10 cm.

❍ We need to find the αreα of the rectαngle.

___________

Areα of the rectαngle = $\large{\boxed{\sf{\orange{Length\times Breadth}}}}$

:$\implies{\sf{15cm\times10cm}}$

:$\large\implies{\boxed{\sf{\red{150cm^{2}}}}}$

• Hence, the αreα of the rectαngle is 150cm².

And we are done!

For Square

Perimeter = 4α

Areα = α²

Cube's volume (3D shape) = α³.

Cube's T.S.A = 6α²

Cube's L.S.A = 4α²

For Rectαngle

Perimeter = 2(l+b)

Areα = l*b

Cuboid's volume (3D shape) = l*b*h

Cuboid's T.S.A = 2(lb+lh+bh)

Cuboid's L.S.A = 2(lh+bh) or 2(l+b)h

For circle

Perimeter or Circumference = 2πr

Areα = πr²

Sphere's volume (3D shape) = 4/3πr³

Sphere's T.S.A or C.S.A = 4πr²
