Question

help pls its urgent ​

Answer 1

Answer:

20 units

Step-by-step explanation:

In the figure a = 3 units and b = 4 units

and in triangle LPQ

LP = a = 3

LQ = b = 4

PQ= ?

it is a right angle triangle. so we can find PQ by hypotenuse method

PQ = root ( 3² + 4²)

PQ = root 25

PQ = 5 unit

We got the one side of the Square PQRS.

now perimeter = 4 × side

Perimeter = 4×5 => 20 units.

Answer 2

Answer:

in triangle LQP

using pythagoras theorem

h²=b²+p²

h² = 3²+4²

h² = 9+16

h²=25

h = 5

PQ = 5 units

in triangle PMS

h²=b²+p²

h²=3²+4²

h²= 9+16

h²=25

h=5

PS = 5 units

PQ, PS are sides of square PQRS

perimeter of square = 4a

= 4×5

= 20 units
