Question

3. A rectangular field is 25 m in length and 18 m in width. Two mutually perpendicular roads, each
3.5 wide, are drawn inside the field so that one road is parallel to the length of the field and the other road is parallel of its width . calculate the area of crossroads​

Answer 1

Answer:

138.25

Step-by-step explanation:

Area of ABCD(1st Road) = 18×3.5 = 63

Area of MNOP(2nd Road) = 25×3.5 = 87.5

Area of QRST(3rd Road) = 3.5×3.5 = 12.25

Area of crossroads = Area of ABCD+Area of MNOP-Area of QRST

= 63+87.5-12.25

= 138.25

Answer 2

Answer:

138.25

Step-by-step explanation:

18×3.5=63

25*3.5=87.5

3.5*3.5=12.25

63+87.5+12.25

=138.25
