Question

For the rectangular room ,area/length=______​

Answer 1

Answer:

length × breadth is the answer

Answer 2

Area of rectangle ⟹ ( L × B )

══════════════════════════

Some more formulas :-

• perimeter of rectangle = 2 ( L + B )

• Perimeter of square = 4 × side

• Area of square = $\rm\red {(side)^{2}}$

• Area of circle $\bigcirc$ = $\rm\red{ \pi {r}^{2}}$

• Circumference of circle $\bigcirc$ = $\rm \red{2\pi {r}^{2}}$

• Volume of cylinder = $\rm\red{ \pi {r}^{2}h}$

• Volume of cuboid = L × B × H

• Volume of Cube = $\large\rm\red{{a}^{3}}$

• CSA of cube = $\large\rm\red{4{a}^{2}}$

• CSA of cuboid = 2H ( L + B )

• CSA of cylinder = $\rm\red{ 2\pi rh}$

• TSA of cube = $\rm\red{6{a}^{2}}$

• TSA of cuboid = $\rm\red{2(LB + BH + LH)}$

• TSA of cylinder = $\rm\red{ 2\pi {r}^{2}h}$

Note :-

• CSA/ LSA = Curved surface area / lateral surface area.

• TSA = Total surface area.
