Answer 1

Step-by-step explanation:

Diagonal of rectangle (d) = 10 cm

Length (l) = 4/3 Breadth (b)

$d \: = \sqrt{ {l}^{2} + {b}^{2} }$

squaring both side

${d}^{2} \: = {l}^{2} + {b}^{2}$

${10}^{2} = {( \frac{4}{3}b) }^{2} + {b}^{2}$

$100 = \frac{16}{9} {b}^{2} + {b}^{2}$

$100 = \frac{25}{9} {b}^{2}$

${b}^{2} = \frac{900}{25}$

$b \: = \frac{30}{5}$

$b \: = 6$

$l \: = \frac{4}{3} \times 6$

$l \: = 8$

perimeter of rectangle = perimeter of square

2 ×(l + b) = 4 × side

$2 \times (8 + 6) = 4 \times side$

$2 \times 14 = 4 \times side$

$28 = 4 \times side$

$side \: = \frac{28}{4}$

$side \: = 7$
