$In$ evaluating a double integral over a region $D,$ a sum $of$ iterated integrals was obtained $as$ follows:

${}_{D}f(x,y)dA={\displaystyle \underset{0}{\overset{5}{}}}{\displaystyle \underset{0}{\overset{y}{}}}f(x,y)dxdy+{\displaystyle \underset{5}{\overset{10}{}}}{\displaystyle \underset{0}{\overset{10-y}{}}}f(x,y)dxdy$

Sketch the region $D$ and express the double integral $asan$ iterated integral with reversed order $of$ integration.

${\displaystyle \underset{a}{\overset{b}{}}}{\displaystyle \underset{g_1(x)}{\overset{g_2(x)}{}}}f(x,y)dydx$

$a=$

$g_1(x)=$

$b=$

$g_2(x)=$
