Question

Find the perimeter and area of a plot whoselength and breadth are 7 m 50 cm and 4 m 40 cm respectively​

Answer 1

Answer:

Perimeter: 2380cm Area: 330000

Step-by-step explanation:

-Perimeter:

2(L+B)

=2(759+440)

=2(1190)

=2380cm

-Area:

L×B

=750cm×440cm

=330000cm²

Answer 2

Step-by-step explanation:

first convert the numerical value to cm than perimeter=2(l+b) put this formula to find the perimeter, area =l×b put this formula to find the area of required plot . 7m5cm =705 cm,4m40cm =440cm . area of plot =2(l×b) ,2(705 +440)= 2290cm perimeter of required plot. Area of plot =(l×b) ,(440×705)=3,10,200cmsquare
