⟹ ⁣Question :-

find the lateral surface area and total surface area of the following :-

l = 25cm

b = 12cm

h = 10cm

⟹ To find :-

LSA ( lateral surface area ) of rectangle

TSA (total surface area )of rectangle

⟹ Formulas :-

LSA = 2h ( l + b )

TSA = 2 ( lb + bh + lh )

⟹ Given :-

length = 25 cm

breadth = 12 cm

height = 10 cm

⟹ Solution :-

⟹ $lateral \: surface \: area \:$

⟹ $2h(l + b)$

⟹$2 \times 10(25 + 12)$

⟹$20(2 5 + 12)$

⟹$20 \times 37$

⟹$740$

⟹$total \: surface \: area \:$

⟹$2(lb \: + bh \: + \: lh \: )$

⟹$2(25 \times 12 + 12 \times 10 + 25 \times 10 \: )$

⟹$2(300 + 120 + 250)$

⟹$2 \times 670$

⟹$1340$

Answers :-

LSA - 740 cm

TSA - 1340 cm
