6x + 20

Explanation:

• To find :-

Perimeter of rectangle

• Given :-

Length = 2x + 7

Breadth/width = x + 3

• Solution :-

We know that

`\mathfrak {perimeter \: of \: rectangle =2(length + breadth) }`

Now we will substitute the values of length and breadth

`\sf \longmapsto perimeter = 2 \{(2x + 7) + (x + 3) \} \\ \\ \\ \sf \longmapsto perimeter = 2 \{3x + 10 \} \\ \\ \\ \sf \longmapsto perimeter = 6x + 20`
