Question

the length and breadth of a rectangle are in the ratio 4:3 and the diagonals measures 10 cm. Find it's perimeter.​

Answer 1

Step-by-step explanation:

Let the length and breadth be 4x and 3x respectively . Now Diagonal is 10cm . ↪Breadth = 2 × 3 = 6cm . ⭐From (1) perimeter = 14 × 2 = 28 cm

Answer 2

Answer:

choose a ∆ and apply Pythagoras theorem

100= 16x^2+9x^2

100=25x^2

x=2

2(4(2)+3(2))=28
