Question

Mr.Sharma bought a rectangular field.Its length was (x+7) and breadth is (x+3).A few years later he bought a plot of land next to the rectangular field.Its area was y^(2)+10y+25.Find the area of the rectangular field.​

Answer 1

Answer:

Length of rectangular field=(x+7)

Breadth of rectangular field=(x+3)

Area of rectangular field=2(l+b)

=2((x+7)+(x+3))

=2(x+7+x+3)

=2(x+x+7+3)

=2(2x+10)

=4x+20

Area of plot bought=y²+10y+25

Area of tatol field=(4x+20)+(y²+10y+25)

=4x+20+y²+10y+25

=y²+10y+4x+20+25

=y²+10y+4x+45
