Question

Find breadth when
length-1.5cm
breadth-?
height-50cm
surface area-5.5m^2

Formula
TSA=2(length×breadth+breadth×height+ height×length)​

Answer 1

Breadth = $\boxed{ \bf\ 5.325 cm }$

$\bf\underline{\underline{ Given :- }}$

• Length = 1.5 cm =

• height = 50 cm

• TSA = 5.5 m² = 55000 cm ²

$\bf\huge\underline{\underline{ To \: Find:- }}$

• Breadth

$\bf\huge\underline{\underline{ Answer :- }}$

• length = l , breadth = b , height = h

• TSA = 2 ( lb + bh + lh )

• TSA/2 = b ( l + h ) + lh

• 55000/2 = b ( 1.5 + 50 ) +( 1.5 × 50)

• 27500 = 51.5 b + 75

• 51.5 b = 27425

• 51.5 b = 27425

• b = 532.52 × 100 / 10000

• b = 5.325 cm

$\rule{10cm}{0.05cm}$

breadth = 5.325 cm
