Question

please answer the above Q . ​

Answer 1

Answer:

h = 4√104/3

Step-by-step explanation:

let l = 2x, b = 3x and h = 4x

therefore, tsa = 2(6x²+12x²+8x²)

= 72x²

now,

72x²(9.5) - 72x²(8) = 1248

=> 72x²(1.5) = 1248

=> 72x² = 1248(2/3)

=> 72x² = 832

=> x² = 832/72

=> x² = 104/9

=> x = √104/3

since h = 4x

=> h = 4(√104/3)

=> h = 4√104/3
