Answer:
If the perimeter of a semicircle is numerically equal to its area (m. square), what is the length of its diameter? Perimeter of a semicircle=pi*d/2+d=d*(pi/2+1), where d is the diameter of the semicircle. => d=8*(pi/2+1)/pi=4+8/pi=6.5465units (approx.)

Answer:
perimeter of semicircle= πr
area of semicircle = π/2 × r²
Step-by-step explanation:
ATQ,
perimeter of semicircle= area of semicircle
π ×r = π /2 × r²
r = 2
since, Diameter= 2× radius
Diameter = 2× 2
= 4
