ÁREA E PERÍMETRO | RESOLUÇÃO DE PROBLEMAS (EXERCÍCIOS NA PRÁTICA)

In this video, we will solve problems involving the area and perimeter of squares, rectangles, and triangles. Learn step-by-step in practice. The questions are as follows: 1) What is the perimeter of a square with an area of ​​36m²? 2) A rectangular plot of land measures 25m by 12m. The owner wants to fence it with wire, making 3 complete turns. Knowing that the wire costs R$ 5 per meter, calculate the total cost. 3) A square has the shape of a rectangle 30m × 20m, but inside it there is a square garden with sides of 10m that cannot be used. Calculate the usable area of ​​the square. 4) A rectangle has a width of 12m and an area of ​​72m². What is its perimeter? 5) A plot of land has an "L" shape, formed by a rectangle and a square. The rectangle has dimensions 20m by 10m, and the square attached to the rectangle has sides of 10m. a) The total area b) The external perimeter 6) A plot of land is formed by: A rectangle of 20 m × 10 m A triangle on top with a base of 20 m and a height of 8 m Calculate the total area. 7) A square plot of land has an area of ​​400 m². Inside it, a strip (like a frame) with a width of 2 m is built around it, leaving a smaller internal area. Calculate: a) the side of the original square b) the side of the internal region c) the area of ​​the constructed strip 8) Calculate the area of ​​the figure below.
