i will ark brainliest if u help . step by step do it

Answer 1

Answer:

2500 cm. sq

Step-by-step explanation:

length of the rectangular garden=40cm

area of ,, ,, ,, ,, ,, ,,, ,,,=1200sq.cm

breadth= area/length

breadth=1200/40=30

length of diagonal= ??

here we use pythagoras theorem

so diagonal sq.=length.sq+breadth.sq

diagonal sq. = sq of 30 +sq of 40

diagonal sq. = 900+1600

diagonal sq.=2500

diagonal=sqrt of 2500

diagonal =50

square field drawn on its diagonal =50X50

=2500cm.sq.

Answer 2

Answer:

2500 Sqcm

Step-by-step explanation:

Let the number be 100x + 10y + z. Reversed number be 100z + 10y + x. x + y + z = 11 … (1) 100z + 10y + x = 5(100x + 10y + z) + 46 100z + 10y + x = 500x + 50y + 5z + 46 499x + 40y – 95z -46 … (2) x + 2y = z x + 2y – z = 0 … (3)
