2. P 10 cm Q T Rajah di sebelah menunjukkan segi tiga sama kaki PQT dan segi empat sama QRST. Luas segi tiga PQT ialah 48 cm2 dan tingginya ialah 8 cm. The diagram shows an isosceles triangle PQT and a square QRST. The area of the triangle PQT is 48 cm² and its height is 8 cm. (a) Hitung luas, dalam cm?, segi empat sama QRST. Calculate the area, in cm?, of the square QRST. (b) Cari perimeter, dalam cm, seluruh rajah itu. Find the perimeter, in cm, of the whole diagram. R​

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

you need to give us more information since we can't answer

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
