breadth

The area of a rectangle gets reduced by 9 square units, if its length is reduced by 5 units and breadth is increased by 3 units. if we increase the length by 3 units and the breadth by 2 units, the area increases by 67 square units. find the dimensions of the rectangle.

Let Length of rectangle be x units & Breadth of rectangle be y units Hence, Area = Length × Breadth Area = xy Given that, Area gets reduced by 9 square units, If length is reduced by 5 units and breadth increased by 3 units So, New Area = New Length × New Breadth Old Area − 9 = (Length − 5) × (Breadth + 3) xy – 9 = (x – 5) (y + 3) xy – 9 = x.

The length of a rectangle is double of its breadth. if its perimeter is 72 meters, find its area.

The sum of the length breadth and height of a cuboid is 6 root 3

Solution Verified by Toppr Correct option is C) Let l,b,h, be the length, breadth and height of the cuboid. ∴l+b+h=19 and l 2+b 2+h 2=5 5 ⇒l 2+b 2+h 2=(5 5) 2=125 Surface area of the cuboid =2(lb+bh+lh) =(l+b+h) 2 - (l 2+ b 2+ h 2) = 19 2 - 125=361−125=236 cm 2 Was this answer helpful? 0 0 Similar questions
