Question

find the area of cross roads with width 3m in a park of length 20m and width 10 m

Answer 1

Answer:

length into width \breadth

so, 20 into 10 = 200

Answer 2

Answer:

$\huge \underline \mathcal \color{red} {Answer↓}$

81m²

Step-by-step explanation:

$\huge \underline \mathcal \color{red} {Given,}$

Length of the park = 20 m

Breadth of the park = 10 m

Width of the cross roads = 3 m

$\huge \underline \mathcal \color{red} {To\:Find,}$

Area of the cross roads

$\huge \underline \mathcal \color{red} {Procedure,}$

Here, We have,

JK = 3m, JL = 10m

EF = 20m, EG = 3m

PQ = 3m, PS = 3m

Area of the cross roads = Area of JKLM + Area of EFGH - Area of PQRS

= JK × JM + EF × EH - PQ × PR

= (3 × 10 + 3 × 20 - 3 × 3) m²

= (30 + 60 - 9) m²

= (90 - 9) m²

= 81 m²
